Definitions

  • the present invention relates to a device for mixing orthopaedic bone cement or the like.
  • Orthopaedic bone cement is used throughout the world ; 5 to secure hip, knee and other metallic prostheses in an appropriate anatomical position.
  • the bone cement is produced by thoroughly mixing together two components, usually methylmethacrylate monomer liquid and polymethylmethacrylate powder. The mixing is usually 10 carried out using a simple bowl and spatula. The surgeon then removes the required amount of cement and manipulates it by hand before inserting it into a preformed cavity or applying it to a resected bony surface where the prosthesis is to be positioned. Cement 15 may either be applied by hand or may be put into a syringe and applied thereby.
  • this simple mixing method has two major drawbacks.
  • air is naturally introduced into the mixture since air is inherently existent within the powder and also in and around the mixing vessel. Air bubbles are also produced by the "boiling off" of monomer which occurs during the mixing process.
  • the introduction of air produces a weak cement and r since the joint must usually support a heavy load, it is important to reduce the amount of air in the mixture as much as possible in order to improve the mechanical strength of the cement material.
  • Bowl mixing devices have been proposed which comprise a mixing bowl with a lid.
  • a mixing paddle extends from the lid into the bowl and is rotated by means of a handle on the outside of the lid.
  • a vacuum source is connected to the bowl to create a vacuum in the mixing bowl.
  • this device has been found to be inadequate in that •dead spots' , i.e. areas where the components are not sufficiently mixed, occur, particularly in the middle of the bowl.
  • mixing paddles may also be a tendency for mixing paddles to break when faced with the xshallenge of a high viscosity material.
  • a hand-held mixing device for bone cement or the like comprising- an enclosed mixing chamber, a port in a wall of said chamber for connection to a vacuum source in use to enable a vacuum to be created in said chamber, a mixing paddle extending into said chamber, and a rotatable handle coupled to said paddle by a gear mechanism arranged such that rotation of said handle causes said paddle to rotate about its own axis and also moves the axis of rotation of the paddle within the chamber whereby the paddle is moved around substantially the entire cement containing region of the interior of the chamber.
  • an improved mixing action may be achieved in e.g. a bowl type mixing device which,mixes the cement thoroughly and can be used more effectively than known devices to mix both small and large quantities of cement.
  • the gear mechanism is a step-up gear such that a single rotation of the handle produces a plurality of rotations of the paddle about its own axis.
  • the drive mechanism for moving the axis within the chamber may vary, as indeed may the path of such movement, it is preferred that the pivot axis is coupled to the handle in such a way that it describes a circle with each rotation of the handle causing a single planetary rotation of the pivot axis about the axis of rotation of the handle.
  • the number of stepped up rotations of the paddle about its own axis produced by a single rotation of the handle is not a whole number so that the paddle ends up in a different orientation after each turn of the handle to increase the mixing efficiency and avoid dead spots.
  • the chamber should preferably be completely sealed from the surrounding environment when in use.
  • a preferred structure comprises a hand-held mixing bowl with a removable lid which fits over the bowl and can preferably be locked to ensure the lid is held securely on the bowl during mixing.
  • the handle is rotatably mounted in the lid and extends outwardly therefrom to be rotated by the user.
  • a seal may also be provided between the lid and the rim of the bowl to ensure that the mixing chamber is completely air-tight and that no fumes can escape.
  • the form of the gear mechanism may vary.
  • the paddle is carried by an axle which is eccentrically coupled to the handle as discussed.
  • a circular rack fixed to the underside of the lid, and arranged coaxially with the rotation axis of the handle, drivingly co-operates with a cog wheel associated with the paddle to rotate the paddle as the handle is turned.
  • a mixing paddle comprising a shaft and a plurality of vanes extending outwardly from the shaft. At least one vane should, for best results, extend out to the edge of the bowl and conform to the shape of the interior of the bowl; other vanes may extend into the bowl by different amounts.
  • the paddle both moves around the bowl and rotates about its own axis r even a single vane could provide thorough mixing in smaller systems.
  • a guide groove may be provided in the base of the mixing bowl in which the base of the paddle, or its axle, is supported as it rotates around the bowl. This groove anchors the paddle and keeps it upright even when the cement thickens.
  • the surgeon can observe the cement during mixing without interrupting the mixing process or exposing the cement to air. Therefore it is preferable that the bowl is transparent or has a transparent window through which the cement can be observed.
  • gases emitted from the mixture are drawn off through a valve and filter arrangement which may comprise a separate, one-way valve and a charcoal filter, or an integrated valve/filter comprising a fibre material impregnated with activated charcoal.
  • a valve and filter arrangement which may comprise a separate, one-way valve and a charcoal filter, or an integrated valve/filter comprising a fibre material impregnated with activated charcoal.
  • a filter means itself represents a new departure.
  • the outlet port for evacuating the chamber may be provided in the bowl or in the lid in the preferred embodiment, and preferably includes a male push fit or other connector for engagement in use with a hose leadin to a vacuum pump.
  • a mixing system for bone cement or the like comprising a mixing chamber, a mixing paddle extending into said chamber, a handle rotatably mounted with respect to said chamber, said handle being connected to said paddle to cause rotation of said paddle, means for evacuating air from said chamber comprising a port in a wall of said chamber ai. ⁇ a vacuum pump connected to said port, filter means adapted to rem ⁇ * unwanted fumes from air removed from said chamber, said filter means comprising either an activated charcoal medium or non- woven fibre material impregnated with a filtering substance such as activated charcoal.
  • the invention provides a mixing system for bone cement or the like comprising an enclosed mixing chamber communicating with a vacuum pump for removing air from the chamber in use, and a mixing mechanism comprising a mixing paddle driven by a handle which causes rotation of the paddle about an axis and simultaneously causes movement of the axis within the chamber.
  • the invention provides a method of mixing bone cement or the like within an evacuated environment, which comprises moving the axis of a rotating mixing element within the mixture during mixing.

  • Fig. 4 shows the gear mechanism of the device of Fig. 1;
  • Fig. 5 shows a cross-section of a preferred embodiment of the mixing device including an integral valve/filter assembly.
  • the mixing device comprises a mixing bowl 1 having a base 2 and an open top.
  • a lid 3 is adapted to fit and seal the top of the bowl 1.
  • the lid 3 is provided with a handle 4, rotatably mounted in, and extending outwardly from the lid 3.
  • the under side of the lid is provided with a fixed, circular, toothed rack 5 which is coaxially arranged with respect to the rotation axis A of the handle.
  • a socket 6 is provided in the underside of the handle 4, eccentrically with respect to the central axis A.
  • the dev: ⁇ * e also includes a mixing paddle 7 mounted on an axle 8 supporting mixing vanes 9 extending outwardly therefrom.
  • the axle 8 is r atably mounted, at one end, in the socket 6 in the handle 4.
  • the other end of the axle 8 fits into a circular groove 10 around the base 2 of the bowl 1.
  • a cog wheel 11 is fixedly attached to the upper part of the axle 8 for intermeshing engagement with the toothed rack 5.
  • the lid 3 is also provided with a vacuum port 12 for connection to a vacuum pump (not show .
  • the lid 3 is preferably provided with a seal 13, for sealing between the lid 3 and the rim of the bowl 1, and locking means 14 to hold the lid 3 securely in place during mixing.
  • the substances to be mixed are placed in the mixing bowl 1.
  • the lid 3 is then placed on t ⁇ ⁇ bowl and locked.
  • the vacuum port 12 is connected, via a length of PVu tubing 15, to a vacuum pump (not shown) to create a vacuum in the bowl 1.
  • the preferred operating vacuum is in the range of 0.7 to 0.9 bar, and is most preferably 0.75 bar.
  • rotation of the handle 4 causes the paddle 7 to move around the bowl 1 in planetary fashion and, at the same time r to rotate about its own axis.
  • Such a mechanism enables the paddle 7 to rotate several times for each turn of the handle 4 and results in a more than 90% coverage of the bowl area.
  • One rotation of the handle 4 does not cause a whole number of rotations of the paddle 7, such that the paddle 7 is in a different orientation at the beginning and end of a particular cycle of the axle movement; this helps to avoid dead spots being formed in the cement and improves mixing.
  • At least one of the vanes 9 should extend from the axle 8 to the wall of the bowl 1; other vanes 9 may only extend partway across the bowl l.
  • the base of the axle 8 travels around the bowl 1 in a groove 10 provided in the base 2 of the bowl to provide support, strength and stability to the paddle 7.
  • the groove 10 ensures that the paddle 7 always remains upright and does not bend when the cement becomes thick.
  • the mixing bowl 1 is preferably made of clear plastic to enable the user to observe the progress of the cement as it is mixed.
  • the noxious methylmethacrylate fumes are drawn off through the PVC tubing 15 and filtered. This may be done in the conventional way via a one-way valve 16, which prevents the fumes returning to the bowl 1, and an activated charcoal filter 17.
  • an integrated valve/filter assembly could be used which comprises a non-woven fibre material impregnated with activated charcoal. This is a much more efficient and convenient system which does not involve the use of charcoal granules.
  • the lid 3 is removed and the cement may be directly applied to the bone site by hand or may be transferred to a syringe for syringe application as preferred.
